  2. Total harmonic distortion - Wikipedia

    en.wikipedia.org/wiki/Total_harmonic_distortion

    However, at higher distortion levels the discrepancy becomes large. For instance, a signal with THD F 266% has a THD R of 94%. [4] A pure square wave with infinite harmonics has THD F of 48.3% [1] [14] [15] and THD R of 43.5%. [16] [17] Some use the term "distortion factor" as a synonym for THD R, [18] while others use it as a synonym for THD F ...

    THD [3] uses a specially developed anoscope combined with a Doppler transducer to identify the hemorrhoidal arteries (originating from the superior rectal artery) 2–3 cm above the pectinate line. Once the superior rectal arteries are identified through the Doppler, a suture ligation is performed to effectively decrease the blood flow to the ...
